[mkgmap-dev] Suggestion for multipolygon version of --generate-sea

Hi list, One of the good things about the non-multipolygon version of --generate-sea (--generate-sea=no-mp) is that it generates a land polygon, which for those of us who cannot change the default Garmin yellow colour of the background is very useful. As far as I can tell, the multipolygon version of --generate-sea does not create this land polygon, which is a bit of a drawback. Is there any chance the multipolygon code could be extended to add a land polygon creation option just like the no-mp approach does? Or perhaps it's already there and I just don't know how to apply it? Thanks, -- Charlie
